Actuated Valves
Pressure Independent Control Valves
Sizes: 1/2″ – 6″
Accuracy: The Unimizer® eliminates inaccuracy in ball valves using the Griswold parabolic flow OPTIMIZER®, a device inserted into the ball to achieve Equal Percentage Control characteristics.
Lower Cv Ratings: Achieve the low Cv ratings of a globe valve at the low price of a ball valve, with higher close-off pressure benefits.
Compatibility: Available in female or sweat threaded end connections. Griswold’s Universal Solution offers the widest range of actuator choices in the industry.
Griswold Controls’ Patent Pending 3 Way Ball: Provides true equal percentage flow from the parabolic shape of the Optimizers® at each port, allowing the use of any standard, low-cost actuator.
- Where actuated ball valves or globe valves are used to control flow
- Where mixing and diverting capabilities are required

Smallest Actuated Valve in the HVAC Industry
Compact Actuated Valve
Griswold Controls Streamline Valves are the most compact actuated valve on the market with the actuator motor built directly into the valve housing.
The Streamline Control valve incorporates the original automatic flow limiting cartridge to maintain constant flow even when system pressures change.
The Streamline Zone valve is for actuated control only. The ceramic disc in the Streamline Control and Streamline Zone valves provides bubble-tight close off against high-rise system pressures—the highest close off pressure in the industry.

Temperature Controllers
Motorized Hydronic Valve
Erie’s motorized hydronic valves, the PopTop™, provide convenient, reliable, and easy installation for a variety of heating and cooling applications.
Installation is simple with easy, one-handed removal or engagement of the actuator to the valve body. Push the button and lift—it’s that easy.
Temperature Controllers
Sizes: 1/2″ – 3/4″
VG1600 Series 270° Six-Way Ball Valves are designed to regulate the flow of both hot and chilled water efficiently in response to the demand of a controller in HVAC systems.
The 270° Six-Way Valve substitutes either four through valves or two through valves and one change-over valve. The VG1600 is supplied with control flow disks providing the right flow rate for a wide range of applications.
The valve is operated by a 270° rotary multi-input signal non-spring return actuator.
